dmaengine: owl-dma: fix clang -Wvoid-pointer-to-enum-cast warning
When building with clang 18 I see the following warning:
| drivers/dma/owl-dma.c:1119:14: warning: cast to smaller integer type
| 'enum owl_dma_id' from 'const void *' [-Wvoid-pointer-to-enum-cast]
| 1119 | od->devid = (enum owl_dma_id)of_device_get_match_data(&pdev->dev);
This is due to the fact that `of_device_get_match_data()` returns a
void* while `enum owl_dma_id` has the size of an int.
Cast result of `of_device_get_match_data()` to a uintptr_t to silence
the above warning for clang builds using W=1
